Distributor for viscous fluids with multiple radial; discharge

Abstract

Distributors for viscous fluids, consisting of a central inlet line and at least two valves that are connected radially to the inlet line, each valve having one valve spindle that moves in the axial direction in the cylindrical valve casing and an outlet opening that opens into an outlet line, whereby a flow displacer having a cylindrical bottom part and a conical top part is inserted centrally into the inlet line at the level of the valves, forming a ring gap, and where the cross section of flow is constricted in the outlet opening and then immediately thereafter is enlarged in the outlet line.

We claim: 
     
       1. In a distributor for viscous fluids, consisting of a central inlet line with an inside diameter of f and at least two valves connected radially to said inlet line, each valve having a cylindrical casing with an inside diameter of b, an outlet opening that opens into an outlet line and a valve spindle having a valve head that moves in the axial direction in said casing, said spindle serving to close off said valve, and said valve head engaging a valve seat having a diameter of e in the wall of said inlet line when the valve is in the closed position, said valve spindle leaving said outlet opening just free when the valve is in the open position, the improvement comprising a flow displacer of the height h with a cylindrical bottom part having the height g and a conical top part facing the fluid flow inserted centrally into said inlet line in the area of said valve seat to form a ring gap of the width k around the bottom part of said displacer, where   g=(1.0 to 1.1)·e       h=(1.0 to 1.3)·f     and     k=(0.10 to 0.25)·f       said outlet line being enlarged along a length c to an inside diameter of d immediately following said outlet opening, which opening has a diameter of a, where   a=(0.5 to 0.7)·b       d=(1.4 to 1.9)·a     and     c=(0.8 to 1.5)·a.       
     
     
       2. Distributor according to claim 1, in which said inlet line is enlarged in comparison with f in the area of the flow displacer, the wall of said inlet line forming an angle (α) in the range of 15° to 30° relative to the axis of said inlet line in the area of said conical top part of said displacer, and said enlarged inside diameter of the inlet line being constant in the area of said bottom part of the displacer. 
     
     
       3. Distributor according to claim 2 in which the following approximate relationships hold:   g=1.0·e       h=1.15·f       k=0.19·f       a=0.6·b       d=1.65·a       c=1.33·a     and     α=25°.     
     
     
       4. Distributor according to claims 1 or 3, in which said outlet line has an oval cross section in the area between the circular cross sections a and d. 
     
     
       5. Distributor according to claim 1 in which the base of the bottom part of said displacer is rounded off or beveled adjacent said ring gap. 
     
     
       6. Distributor according to claim 1 in which the distributor is surrounded by at least one heating jacket and said flow displacer has an interior cavity, said heating jacket and said cavity being connected to a liquid heating medium circuit. 
     
     
       7. Distributor according to claim 1 in which said central inlet line is connected radially to at least 3 and up to 8 symmetrically arranged valves. 
     
     
       8. Distributor according to claim 7 in which one of said valves is connected to a discharging unit and the other valves are each connected to a processing unit. 
     
     
       9. Distributor according to claim 8 in which said processing unit is a spinning unit.
